My friends 06 gsxr 1000 is dropped and stretched and his front tire is wearing really quick on the sides. His tire pressure was fine and the front forks were even. Could this be from the front not being low enough?

My 94 RF900 did the same thing and I never bothered to figure it out. That bike was at stock height in the front cuz it was too low in the rear to lower the front. It got hung up on speed bumps as it was.

Thanks,
Frankie
